bug#20100: 24.4.91; Can't scroll a window while in minibuffer

It's a trap.  Commands that implicitly work on the selected window
should not be used programmatically.  Such commands are `recenter',
`enlarge-window', `shrink-window', `split-window-below' and
`split-window-right'.  When used in applications the only way to make
them behave is to wrap them in `with-selected-window' :-(

There are also more specialized commands like `recenter-top-bottom' or
`move-to-window-line-top-bottom' whose doc-strings don't explain what
they do.  Never use them in programs!
